Just noticed a few weeks ago that the speakers in the left side aren't working. All except the tiny one in the trim by the windshield. It is not a bose stereo. I read that it could be an amp issue under the center console. I pulled the receiver out of the dash and the speakers out of the doors, verified everything was plugged in. Cleaned off the contacts and hooked everything back up. They are still not working. Not really looking forward to pulling the center console out to get to the amp, is there anything else it could be before I tear into the center console?
